Professional Applications & Engineering Value

This 18-8 Stainless Steel Thumb Screw is engineered to address critical assembly challenges in industrial settings. The 10-32 UNF fine thread and Class 2A thread fit provide secure, precise engagement in components requiring fine adjustment, reducing the risk of stripping or loosening under vibration. The 1/4" shoulder length with precise tolerances ensures accurate alignment in machinery, acting as a reliable pivot or spacer in assemblies like electronic enclosures, optical devices, and precision instruments. The knurled round head allows for quick manual tightening where tool access is limited, while the hex drive offers backup torque application. Made from corrosion-resistant stainless steel, it performs reliably in moist or chemically exposed environments, extending service life and reducing maintenance needs in industrial thumb screw applications.

Specification Summary & Compliance

This shoulder screw maintains Class 2A thread fit for consistent, precise engagement with standard UNF internal threads. The shoulder features a diameter of 1/4" with a tight tolerance of -0.001" to 0", and a length of 1/4" with a tolerance of 0" to 0.002", ensuring exact positioning. Manufactured from 18-8 Stainless Steel, it meets Rockwell B83 hardness and 70,000 psi tensile strength specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible manufacturing and use.
